Aerodynamics of a Round Jet in a Counterflowing Wind

Abstract

In Chiao's computation8 of nonlinear vortex lift based on Polhamus' suction analogy, he recommended that the projected C.P. was the best arrangement of MFES to calculate suction forces acting on wing side edges. DeJarnette9 had treated the problem of spanwise distribution of control points in 1976. In his paper, the present projected C.P. distribution was called conventional and was quoted to have the same unsatisfied results as the midpanel C.P. arrangement. He had proposed another C.P. arrangement which was almost identical with ours except the positions of panel side and control point were interchanged. But, our work on this subject has already shown that the projected C.P. arrangement is far from conventional, it behaves more superior to the midpanel C.P. When compared with DeJarnette's, the projected C.P. provides the same accuracy and rate of convergence.
